IMPROVEMENT IN GANG-PLOW.

TO ALL WHOM IT MAY CONCERN:

Be it known that we, ANDREW SMITH and WILLIAM P. WATSON, of Portland, inthe county of Multnomah, and State of Oregon, have invented a new andimproved Gang-Plow; and we do hereby declare that the following is afull, clear, and exact description of the construction and operation ofthe same, reference being had to the accompanying drawings, making apart of this specification, in whicli I Figure 1 is alongitudinalvertical section.

Figure 2 is 'a'top view.

Figure 3 is a detached vertical section, showing the adjustable'couplingby which thc plow-beams are connected to the axle. I

The object of this invention is to provide a cheap, convenient, andeasilyadjustable gang-plow, which will clear itself of obstructions andwork easily, the plows swinging freely sideways, so as to avoidobstacles, and being readily elevated out of contact with the soil, whengoing to and returning from' the field.

In the drawings, A A indicate the wheels;.B, the axle; O, thedraught-beam; D, the frame; E, the drivers seat; RF, the plow-beams; .GG', the plow-standards; and H H, the plows.

The forward ends of the plow-beams are hinged to a double or foldedplate, I, which is attached to a vertical plate, J. The top of thelatterplate is provided with a lug-,j, through which a vertical rod, K,passes, cxtendingdown'through the plate I, and through the axle itself.The upper end of thisrod is provided with a crank, It, within'easy reachof the drivers seat; Just below the crank, the rod screws through aplate or hearing, L, so that by turning the crank, it, the rod screws upor down, carrying the plate J up and down, and, with said plate, raisingand lowering the hinge-plate I, and the forward end of the plow-beams,which are attached to the hinge-plate. Different holes a a are providedin the frame D, and the axle, by which the rod K can be set to onesidcer theother, and the plows made to run more or less to land,

The plow-beams are connected by braces 12 I), and a rope or 'chain, 0,attached to them, passes up over a. roller, M, and forward to anotherroller, N, to which the chain is attached, and which serves to wind itup and raise or depress the plows at pleasure. m is a crank-wheel,attached to the end of the roller N, by which to Operate the latter. Itsrim is formedinto a ratchet, and operates in connection with a pawl, p,which prevents it from running back and lowering the plows. Afoot-lever, 1', serves to throw up the ratchet and drop the plows whenneccssaryf v The draught-beam C is capable of swinging slightly on theframe A at 0, and at its rear end is provided with a clcvis, t, havingseveral holes in a transverse line across the frame, so that by boltingthe rear end of the tongue or draught-beam to the axle at one point oranother, the draught of the instrument can be changed at pleasure. Or,instead of this construction, the tongue may befirmly attached to thelower part of the frame, and the latter being made in the form of asemicircle or a horse-shoe, as seen in fig. 1, can be slightly rotatedto one side or the other, and clamped in the new position by thecouplings s s, thus producing the same effectin changing the draught, asis above described. A foot-rest, T, maybe provided, and may be made toswing on a pivot or hinge, so that it can be turned up out of the way ifdesired.

Having thus described our invention, what we claim as new, and desire tosecure by Letters Patent, is

1. The combination of the rod K, plate J, through which the rod Kscrews, and which is attached to the hinge-joint I, hinge-plate I,plow-beams F F, and standards and plows G H, substantially as described.

2. The combination of the hinged beams F F, cordc, rollers M and N,ratchet m, pawl 12, and foot-lever 7', substantially as described. p IAttaching the rea'rcnd of the tongue to the axle, by means of a clevis,t, and ascries of holes arranged as described, by which the draught canbe changed, substantially as above set forth.
